if you are creating CloudFormation template for many customers, it is important to keep the template static and have the customers update the parameter store or the parameterblock on the teplate to suit the region they are working in. Of course the ami's,keypairs,subnet Ids wouldn't be the same, (jsut to name a few)
In this pipeline, your customer doesnt need to update or touch the template but they need to go to the parameter store to update the template
I checked in my template in github but you can use any repository of your choice. The idea is for a pipeline to be triggered from the checking into Github and this is possible by a logic which is configured in Jenkins which in turn will create a cfn stack and provide all the resources specified in your cfn template.
A jenkins image is pulled on the container which is in turn installed on an Ubuntu EC2 instance
here is the template tell me how this goes.Try creating the pipeline, doing first deployment and commiting changes on that same code and see if your pipeline triggers a build.
Rem to install aws cli on the container that you install jenkins
install docker on ubuntu 22 and pull a jenkins image.then run a container creating a directory where you will mount your data incase you restart yout container
1.install from official repo or from default repository https://cloudchamp.notion.site/How-to-Install-Docker-on-Ubuntu-20-f6cda544c64f44ccb83443f8204b098e
#Download Dependencies sudo apt-get install apt-transport-https ca-certificates curl software-properties-common #Adding Docker GPG kEY curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - #install docker repository sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" #install latest Docker, start by updating again sudo apt update docker #verify installation #enable docker service sudo systemctl start docker(to start docker service) sudo systemctl enable docker (enable docker run at startup) #check if service is running sudo service docker status
Installing docker from default repo #update repo sudo apt update #uninstall old versions of Docker sudo apt-get remove docker docker-engine docker.io
sudo apt install docker.io #check installation docker --version suod service docker status
if not running sudo service docker start 2.Pull jenkins image from dockerhub(you must have a dockerhub account) 4. sudo docker image ls (to check if image was pulled) 5. create the directory to store the containers data in case you restart container your data will remain safe). mkdir /var/jenkins_home/
sudo chmod 777 /var/jenkins_home/ -R (bc docker has to write to this directory -R is for recursive) ls 6. docker container ls cd /var/jenkins_home/ docker container ls (copy the container image) docker logs -f contianerimageID copy the initial password and open the jenkins in your browser and use the password
docker run -p 8080:8080 -d -v /var/jenkins_home:/var/jenkins_home jenkins/jenkins
note: on your instance sg donot forget to open the port for jenkins (ICMP, 8080)
